Breastfeeding

I am a parent with a low supply of breast milk. My OB never told me about capsules that can help in incresing my breast milk once I have given birth to my child; I also took contraceptive pills since my OB told me that it is safe during breastfeeding but she never told me that it can drop the supply of my breastmilk.I tried various supplements such as moringa capsules and even tea. I also tried a couple of maternal milk supplements like anmum and mother nurture. How can I increase the supply of my breastmilk?
